Frog

Frogs are a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (Ancient Greek an-, without + oura, tail). The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is found in tropical rainforests. There are approximately 4,800 recorded species, making them among the most diverse vertebrate groups.

Famous quotes containing the word frog:

“In almost all climes the tortoise and the frog are among the precursors and heralds of this season, and birds fly with song and glancing plumage, and plants spring and bloom, and winds blow, to correct this slight oscillation of the poles and preserve the equilibrium of nature.”
—Henry David Thoreau (1817–1862)

“What a wonderful bird the frog are—
When he stand he sit almost;
When he hop, he fly almost.
He ain’t got no sense hardly;
He ain’t got no tail hardly either.
When he sit, he sit on what he ain’t got almost.”
—Unknown. The Frog (l. 1–6)

“A frog he would a-wooing go,
Heigh ho! says Rowley,
Whether his mother would let him or no.
With a rowley, powley, gammon and spinach,
Heigh ho! says Anthony Rowley.”
—Mother Goose (fl. 17th–18th century. A frog he would a-wooing go (l. 1–5)
